Error on require

[Paul Rumkin]

Got error requiring cjson:

/apps/nginx/lua-cjson/cjson.so:1: unexpected symbol near 'char(127)'

cjson was built with command:

make LUA_INCLUDE_DIR=/usr/include/lua5.2

The error indicates that "cjson.so" is being interpreted as a Lua source file, not a plugin.

I'm not familiar with your nginx configuration, but I suspect the Lua package.path incorrectly includes the "?.so" file. Eg:

$ lua
Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
> package.path = "./?.so"
> require "cjson"
error loading module 'cjson' from file './cjson.so':
    ./cjson.so:1: unexpected symbol near char(127)
stack traceback:
    [C]: in ?
    [C]: in function 'require'
    stdin:1: in main chunk
    [C]: in ?

The path settings can usually be set with LUA_PATH/LUA_CPATH environment variables, package.path/package.cpath (within Lua), or some custom application configuration (Nginx).

Yep, it works. I've mixed up path and cpath. Sorry for that and thanks for answer!

And now I've got )

lua-cjson/cjson.so: undefined symbol: luaL_setfuncs

[Paul Rumkin]

Solved.
